Thank you for your reply. I just wanted to state that from the time that I was 26 through 34 years of age, I had a lot of hair growth on my back and upper arms. The hairs would grow very long and they would grow back very fast after I shaved them. I estimated that I have been through almost 345 hours in total for electrolysis treatments. So you still believe this is a normal time frame for hair removal for both full back and upper arms? For some reason I still feel like I could have wrapped this up in half the time if I went for 2x a week sessions for 1 hour over the course of 4 to 5 years. Just curious about your take on this.
